ELEVATOR AND CARRIER.

Specification of Letters Patent.

'ratented July 31, 1906.

Application filed December 23, 1901. $erial No. 37,029.

To (Li/Z whom, itmay concern:

Be it known that I, JOHN M. BOYD, a citizen of the United States, residing at Fond du Lac, in the county of Fond du Lac and State of Wisconsin, have invented certain new and useful Improvements in Elevators and Carriers, of which the following is a specification.

My invention relates to improvements in elevators and carriers adapted to run upon a track suspended in the peak of a barn or in other places where it is desired to elevate hay or other material and to deliver it at different points along underneath the track, and has for its object to provide an apparatus of simple, strong, and durable construction, easily and quickly put up and secured in place, and sure, safe, and easy in operation, whereby the handling of the hay or other material may be greatly facilitated and whereby the same may be filled in close up to the peak of the rafters or other point from which the track is suspended easily and quickly without the straining and cramping of the track and carrier as ordinarily constructed; and it consists in the improved construction, combination,and arrangement of the various parts, substantially as shown in the drawings and pointed out in the claims.

In the accompanying drawings, in which similar letters of reference indicate corresponding parts, Figure 1 is a side elevation of the elevator and carrier and track, part of one side of the carrier being broken away to show the interior parts. Fig. 2 is an end view of the carrier and track with one of its supporting hanger-hooks, partly in section on line as as of Fig. 1, and showing the upper pulley partly broken away to show the fork or trip pulley and its frame, also partly in section. Fig. 3 is a detail view of one end of one side of the stop or trip block for the carrier and of the adj usting wedge or cam for same. Fig. 4 is a detail view of the hook to be attached to the fork or trip pulley, as in Figs. 1 and 2. Fig. 5 is a view of the closing-link for said hook and of the spring for holding the same in a closed position. Fig. 6 is a detail view, partly in section, of means for adjusting the journals of the wheels endwise. Fig. 7 is a detail view of the cross-tie or end support in the carrier-frame and Fig. 8 is a detail view of means for connecting two hooks instead of one to the fork-pulley when desired, &c., as hereinafter pointed out.

In the drawings, 9" 1" represent the rafterbrackets adapted to be attached to the rafters or other supports in the ordinary manner.

h h are the hanger-hooks or track-hangers adapted to be hooked into the rafter-brackets r 1" or other support, as in Figs. 1 and 2, to support the rail or track and'allow it to swing sidewise in the usual manner, said track being preferably formed, as shown, of a single rail T, provided with lower side flanges for the wheels of the carrier to run upon and an upper bead whereby it may be suspended by the said hanging hooks h 7L, (though other styles of track-rail provided with suitable bearings for the wheels and means for support may also be. used.)

8 is the stop or trip block of the carrier, being preferably formed in two sides or plates to be bolted on opposite sides of said track-hangers, the upper central part of said stop-block being cutaway to allow the rafter-brackets to pass through and to allow said stop to be ad justed endwise according to the width or thickness of the rafters and in line with the hanging hooks, said rafter-brackets and hangers being attached to both sides of the rafters at the point where the stop is attached and adjusting cams or wedges d d, Figs. 1, 2, and 3, being placed between the ends of the sides or plates of the stop and held in place by the bolts passing through the ends of said'stop and by the guide-lugs b, Fig. 3, on the inner sides of the ends of the sides or plates of the stop projecting into the slot formed in said adjusting cam or wedge to allow it to be adjusted up and down to provide for rafters of different thickness and allow it to bear against the back of the hangers, as in Figs. 1 and 2, to hold against the endwise strain on the stop, said sides of the stop being also held together by a bolt passing through the center of said sides near the lower edge between the hangers, if desired, said hangers being preferably formed with lateral extensions, lugs, or guides h 71, to support said stop, as in Figs. 1 and 2. (See also divisional application for suspended track, filed May 20, 1903, Serial No. 158,010.) By this arrangement it will be seen the strain on the stop-block is thrown up against the rafters instead of leaving it on the track, as ordinarily constructed, where the stop-block is attached to the track, and being up against the top of the hangers neXt to the rafters it also saves considerable strain or leverage on the hangers and allows the carrier-wheels w w to pass underneath the side extensions or inclines of the stop without the construction of a web or extension to hold said stop up from the track and the body of the carrier to be brought up close underneath the rail or track, no space being required for a stop underneath the track. This stopblock 8 is also provided with guide-lugs or inclines Z Z on each side adapted to engage with inwardly-projecting lugs c on the upper end of a bifurcated catch-block c, preferably sliding vertically up and down in guideways formed in the carrier-frame, the sides of said catch projecting up each side of the rail or track, as shown, and the lower end or crossiece 0 Fig. 2, engaging with a grapple-hoo 7r, Fig. 1, dropping infront of an upper extension of said hook and locking it to t e head or trip f of the fork-pulley or trip-pulley frame f, as in Fig. 1, when the carrier is released from the stop and being locked or held up against the upper lugs or inclines Z Z of the stop by said upper extension of said grapple-hook 76 when in engagement with the stop, said catch 0 being raised up by the lower or long inclines Z Z of the stop engaging with the inwardlyrojecting lugs c c, Fig. 2, at the upper en of the catch as the carrier approaches the stop from either di rection, thus releasing the grapple-hook is, which tips forward by its own gravity underneath said catch or is pulled over by the weight of the fork-pulley frame f and tackle, thus locking said catch up between the upper lugs or inclines Z Z of the stop (similar to the device shown in my former patent, No. 300,687, and now in quite general use) and holding it up in engagement with either of these upper lugs, according to the direction of the strain or pull upon the draft-rope, while the load is being elevated (the device being adapted to work equally well in either direction from the stop) until the head or trip f of the fork-pulley f enters the carrier and drives the hook 76 back into its former position, as in Fig. 1, thus releasing said catch 0, when said catch will drop down, or the force of the draft against the inclined faces of the upper lugs of the stop will force it'down in front of the up er extension of said grapplehook, thus loc 'ing said hook as heretofore, and the elongated or lower outer upturned extensions, of said upper lugs Z Z will prevent thecatch rebounding or s ringing up as its lower end is. suddenly pinc lied by the upper end or extension of the hook as the carrier leaves the stop and the load comes on said hook, especially when worked very quickly.

y y'are the rope or guide pulleys, which are carried on a collar or band swiveled around the lower part of the main frame or body of the carrier in the usual manner, as shown partly in section in Fig. 1, and provided with upper supports, slides, or bearings e a above the pulleys, adapted to bear against and slide upon cross-ties or end sup ports t t, Figs. 1, 2, and 7, preferably formed with upper extensions t 17, by which they are bolted to downwardly-extending supports or hangers p p at the ends of each side of the carrier-frame a a, thus formin a cross-tie for and connecting the ends 0 said carrierframe and also forming an end support for the pulley-frame or collar, as will be understood, and greatly strengthening the carrier, said cross-tie t t being preferably beveled at each end to receive-the upper supports or bearings e e as the collar is turned around to change the direction in which the load is carried, or roller-bearings may be used in place of the slide-bearings e e if desired.

f is the fork-pulley or trip-pulley frame formed with a head f 7 or other form of trip at its upper end to engage the grapple-hook in the carrier in the usual manner, (or being otherwise adapted to trip the carrier as the load is raised but instead of attaching the hook or clevis which carries the load to a downward extension or loop of said frame in the usual manner I pivot said hook f between the lower ends of two arms, hangers, or side links f which in turn are also pivoted at their upper ends in bearings in the sides of the pulley-frame f at the sides of the sheave or pulley, preferably below its center and above its lower edge, as in Figs. 1 and 2, thus allowing the hook to swing out or fold up at one side of the pulley-frame, as in Fig. 1, and greatly save the strain and jerk or cramping and leverage on the carrier and pulley frames as the carrier starts off suddenly from the stop with its load after beingtripped or when pulling hay into a mow nearly full, &c., as

will be readily understood. The head of the hook f 3 is also provided with a slot or recess 1; across its top, (see Figs. 2 and 4,) and the arms or links f are provided. with holes u a to register with said slot or recess, (or when a rigid pulley-frame is used said holes may be provided in said-frame, as will be understood) through which a small bolt or key may be passed when it is desired to use a stiff hook, as when anew rope is being used, to prevent twisting, said bolt or key being removed as the rope becomes more pliable and a swiveled hook is desired. A closing or safety link f 4 is also attached to the rear upper part of said hook, as shown in Figs. 1, 2, 4, and 5, and extends forward across the open part of said hook and rests upon a shoulder, rest, or guard provided near its point, as in Fig. 4, the sides of said link being' curved outwardly and upwardly to allow it to be opened up against the arms, links, or hangers f when desired to unhook from the fork, &c., and to provide a hook-shaped end to catch over the fork or slinghead, &c., and prevent its jumping out when said link is closed, although allowing said link to give or raise slightly as the fork or sling-head strikes it, said link being held flexibly in closed position by a spring f 5 so it can be easily and quickly opened when desired to release from a fork or sling-head, &c., and, if desired, said link may also be provided with two outwardly and upwardly curved extensions or hooks f f, as shown, which hooks drop one each side of the curved outer end or point of the hook f 3 as the link is closed, when a key may be inserted above said hooks f f and underneath said curved end of said hook f to hold said link rigidly when desired, or these hooks f f may be omitted, if desired.

A modified form of the arms, links, or hangers is shown at F, Fig. 8, forming a sort of clevis which may be used in place of the links f 2 when it is desired to attach two hooks instead of one for use with a hay-sling, &c., or to attach directly to' a fork-head or other article by passing said clevis through said fork head, &c. (See also divisional application filed June 4, 1904, Serial No. 211,220.)

The above fork-pulley, with its hook and other attachments or parts, is also further shown, described, and claimed in my divisional application for Letters Patent for improvements in pulley-blocks, Serial No. 211,220, intended to be issued at same date as this, being a division of this application.

In Fig. 6 means are also shown whereby the journals of the traveling wheels may be adjusted endwise for tracks of different width (as it may be desired to use the carrier on other styles of tracks already put up,) said journal It being provided with a shoulderto rest against a washer or bearings, (01 with a bushing in place of said shoulder,) said washer 3 being formed with a boss or extension adapted to project into an opening or chamber formed inside the upper end of the arm or side a of the carrier, as shown in section in Figs. 2 and 6, other washers s (also shown in section) of the desired thickness being inserted between the outer part of the washer s and said arm or side a of the carrier around said boss when desired, and said journal R being provided with screwthreads and a nut or bur, (or other means in connection with the above,) whereby it may be adjusted and held rigidly in place, as will be understood. It is also evident to any one skilled in the art that these washers may be removed and a plain washer used next to the side or arm a of the carrier for the shoulder of the journal to bear against or that said shoulder maybe allowed to enter into said opening or chamber in the arm a and a wheel with a shorter hub used, if desired, as will be readily understood, or said arm a may be formed with an extension (shown in dotted or broken lines a in Fig. 6) above said washers to give them a better bearing, if necessary, said extension being high enough to allow the hub of the wheel (also shown in dotted or broken lines) to pass underneath it, and that other slight modifications may also be made.

The operation of the different parts and 0f the apparatus as a whole will be readily understood from the foregoing description.

It is also evident that the carrier may be adapted to run on a wood track, and that other modifications may also be made without departing from the spirit of my invention, and that different parts of the apparatus may be used in connection with machines or apparatus different in other respects and for other uses. I therefore wish it distinctly understood that I reserve to myself all such modifications, parts, and combinations as properly come within the scope of my invention and for all purposes for which they may be adapted and useful, having shown what I consider the most desirable form and combination of parts for the purposes set forth.
